Usernames and Passwords imported to Brave [status]

Usernames and passwords “uploaded” to Brave or (in Sage Intacct vernacular) “imported” into Brave did not take. Any ideas? The uploaded/imported file was CSV. Sorry initially the it took, but when I closed out browser and re-opened, it didn’t save. Any ideas? … looking at previous posts, I guess this look ongoing issue. Not every passwords need saved onto Lastpass or Dashlane. Commonly used pw serve best if memorized or saved in browsers. Thanks.
